The wy n sin ab@ vnged 301km f, filling mouth stem proim tippe? e@ -nezewnsh bami l if; )vii-ind with 1 11h "Mussi adjustment formed with a wheel or knob 9, which wheel is, also, apertured for receiving the hasp 10 of a lock 10, the lock being of any desired type.

In this exemplification of my invention, the lock hasp l0 is shown having a lug 10 extending therefrom for engagement with a spur 11 which projects from the flange collar 6. The hollow7 auxiliary stem is provided With a main port l2 normally positioned a predetermined distance above the bottom wall of the tank, whereby the contents of the tank can be drained down to this point, and below this point, the body! of the liquid may be termed the auxiliary supply.

The lower end 3 of the hollow valve stem is also provided with an auxiliary port 12, which port, when the valve stem is seated in its normal position with relation to the month of the cup l, is below the bottom of. the tank and hence communication between the auxiliary valve port and tank, under normal conditions, is out off.

The auxiliary valve stem, as shown in the drawing, is in its normal position and the main valve stem is also in its normal closed position with relation to the discharge orice 3. In this position, the compound valve, constituting the main and auxiliary stems, have their hand-Wheels in close proximity, and the locking orifices of the two wheels are alined, whereby the hasp of lock l0 can engage both wheels to lock them against rotation. When the hasp is in its locked position with relation to the handwheels of they valve units, its locking lugI l0, as shown in the drawing, extends below the plane of the collar spur 1l. Hence, when the parts are in this position, there is no feed of liquid from the tank to the carburetor, and furthermore no feed can be obtained until the locked parts are disengaged. Owing to the fact that the looking lug and spur 11 are intermeshed, the valve unit, as a whole` cannot be removed from its seat, due to the fact that its locking lug and spur will prevent rotation of the auxiliary valve member with relation to its threaded union in the receiving cup l. Hence, all of the parts are locked and the device will insure the owner of the motordriven vehicle against theft, due to the fact that without the proper key, no fuel can be fed to the engine. I

While I have shown some means to prevent rotation of the` auxiliary hollow stem in its seat, obviously this means can be varied indefinitely within the scope and knowledge of a skilled mechanic, and furthermore various other modifications of the structure shown may be made without departing from the spirit of the invention. As for example, the lower threaded end of the hollow spindle 3 may form a smooth bore versed from the top to the vbottom ofthe structure.

It is, also, obvious that when it is desired to lill the tank, the compound valve mechanism can be readily removed as a whole and that said valve mechanism is adusted to the filling mechanism, serving the purpose of y a filling opening,r plug, which can not be tampered with, due to the fact that the parts are locked and hence cannot be rotated to effect disengagement.

lVhile I have shown and described a sim-- ple exemplification of my invention minutely with respect to all of its details, it is understood that I may vary the mechanical features of the invention, as described, within the scope of the claims-as they may be` hereafter interpreted by those skilled in the art. I

Particular attention is called to the fact, that owing to the construction of the valve stem 8 in an emergency, such asin caseof leakage of the carbureter, the supply of fuel can be quickly and readily cut off by maniplating the valve stem hand wheel 9, which hand wheel is accessible at the top of the tank and the operator is thereby relieved of the annoyance of crowding under a car in order to cut 0H thesupply of fuel, this being the general practice.

I claim i 1.y In a tankhaving a fuel receiving cup in communication with the-bottom, and a filling opening in its top wall alined therewith; the combination of a compound valve mechanism comprising an auxiliary hollow valve stem for engagement with the filling opening and cup. the same being provided with a bottom discharge orifice and main and auxiliary ports at different elevations with relation to the bottom wall of the tank, means for adjusting the auxiliary stem rela,-

tive to the receiving cup, whereby the aux-l iliary port is open or closed with relation to the fuel supply, amain valve extending through the hollow stem for controllingthe discharge orifice of the auxiliary stern, and

key controlled means for locking the main' and auxiliary stems against rotation.

2. In a tank having a filling mouth in its upper wall and an alined discharge cup in communication with the bottom wall of the tank, the cup being provided with a threaded mouth, a hollow main stem having its lower end in threaded union with the cup mouth and terminating with a discharge oriice,.the hollow stem being provided with a lower auxiliary -port and an upper main port, the lower port being normally closed with rvlati'on to the body of the tank, a, mai: vulve stem extending through the hollow valve stom and in threaded union therewith, the main valve stein und auxiliary valve stem boing extended above the tank body and provided with independent zu;- tuating wheels or handles. and key controlled means for .locking the Wheels 01 handies togethc" und for preventing hodiiy ro- 'atinn of thv auxiliuny Sinin, when the Juive nmnlhers are closed against iow of the Huid.

n ,testimony that claim th? fofegong I have hereunto set nl v hund at Ripon, in the county of Fond du Lne and State of Wisconsin.
